29-May-2011 -- The place is on a plain to the north of the "Salar de Coipasa" ("Coipasa salt flat"). The soil is sandy with bushes of straw. There are no rivers nearby; however, the ground appears to the bed of a lake. It is a desert landscape in which in the distance you can see some mountains.

We planned the visit to the confluence together with the confluence 18°S 68°W. The plan was to visit it on 29 May and did not seem complicated, but we were concerned about how far it was from anywhere else. The nearest point from a dirt road was 6.3 km south.

Our intention was to get as close as possible before starting the trek. When we approached the starting point, we saw some tracks made by vehicles which appeared to go near the point, so we decided to detour along those tracks.

There were no clouds, the sun was intense and there was no wind, this gave us the confidence of having enough time to approach a little more. The tracks took a course that was no longer appropriate, so from there we started the trek. Getting closer in the vehicle turned out to be very risky because of the sandy soil; we didn’t want to get stuck in the middle of a desert.

Finally, we started the trek at 13:00, without pausing we reached the point at 13:45.
